CINCINNATI - From bomb-sniffing dogs to uniformed military members, runners will notice more security than ever at major events in Ohio's four largest cities in the next month and indefinitely thereafter.
The changes come in the wake of last week's Boston marathon bombings and after a flurry of meetings between Ohio's race organizers, local police and federal authorities.
The bombings killed three people and wounded more than 180.
In Cincinnati, for example, organizers say that overall security will be more than doubled from past events, and for the first time will include bomb-sniffing dogs and uniformed volunteers from the National Guard.
Similar measures are expected at a marathon coming up this weekend in Toledo, at a half-marathon May 4 in Columbus and at Cleveland's marathon May 19.
